ported upon the table during the loading of Be it known that I, HERBERTTALLEY, a the cartridges and removed therefrom when citizen of theUnited States, residing in Carthage, State of Missouri, have inventedcertain new and useful Improvements in Packing-Machines, of which thefollowing is a specification.

My invention relates to the explosive industry, and more particularly tothe manufacture of explosive cartridges or shells; and it particularlyappertains to the means for loading shells with the explosive.

The method and means now commonly employed for loading cartridges withexplosives, particularly high explosives, are attended not only withgreat danger to those employed in this occupation, but with materialloss by way of the destruction to the.

manufacturing plants, owing to the explosions which are occasioned inthe packing of the cartridges when this is done by mechanical means.

Mechanical means have heretofore been employed in packing shells; but insuch devices of which I have knowledge sticks, tamps, screws, or augersworking through funnels or nozzles have been employed for compacting theexplosive mixtures, and it has been found that these means frequentlycause such excessive friction, owing to the presence of hard foreignbodies in the explosive mixtures, as to cause the substance to explode.

Itis the object of my invention to provide a loading apparatus by meansof which the shells may be loaded economically and with minimum dangerof premature explosion and which will not require the presence of theoperatives adjacent the explosive mixture during the loading operation,so that even in the event of an explosion no fatalities need resulttherefrom.

One exemplification of the invention is illustrated in the accompanyingdrawings, in which- Figure l is a longitudinal sectional view throughthe complete apparatus. Fig. 2 is adetail view of the shell-carrier, andFigs. 3 and 4 are detail views.

The invention includes generally a vertically-movable table having meansassociated therewith for giving it a jarring action, a shuttle orshell-carrier, intended to hold a plurality of cartridges, which isdesigned to be supthe latter are filled, a hopper provided/with nozzlesdesigned to register with the shells in the carrier, and means forrigidly connecting the hopper-carrier and table to one another duringthe filling operation.

The movable table is designated a in the accompanying drawings and iscarried at the upper end on a pedestal b. In the particularexempliiication of the invention herein disclosed means utilizing asuitable motive fluid is associated with the table for giving it ajarring action. This means is illustrated as a vertically-disposedcylinder c, arranged beneath the Hoor-line d, in which travels a pistone, carrying the pedestal l). An inlet f for the motive medium is locatedat the bottom of the cylinder, and an exhaust-port g leads from thecylinder a short distance above the inlet-port.

Compressed air or steam is preferably employed as the motive medium, andit is fed intermittently by any desired means through the inlet f andserves to force the piston c upwardly in the cylinder until the end ofthe piston uncovers the port g, whereupon the motive medium is exhaustedand the piston drops back in the cylinder under the weight of the tableand its contents7 the jar received by the piston striking the end of thecylinder being of course imparted to the shell-carrier and the hopper.For controlling the length of stroke of the piston and the severity ofthe j ar imparted to the table an adjustable stop h is preferablyassociated with the piston-head. In the illustrated embodiment of theinvention this element is a bolt having its shank screwed into thepiston and its head arranged to strike against the end of the cylinder.

The shuttle or shell-carrier is designated t' and consists, preferably,of a case or block having a plurality of pockets m therein ofsubstantially the size of the shell to be packed. As will be understood,it is the common practice to pack shells of varying but approximatelystandard sizes or diameters, and consequently my invention contemplatesthe provision of several sets of shell-carriers, each set having pocketsof the proper diameter to snugly iit the size of shell to be employedtherewith. Handles a are preferably provided on the ends of the car- IOOriers for facilitating the transportation of the same. The pockets m areintended to be filled with empty shells in the house where the latterare made, these shells preferably having their upper ends protrudingfrom the pockets, and the carrier so filled is then placed upon the topof the table a.

The hopper is designated o, is provided with a pluralityT ofdischarge-openings in its bottom corresponding in number and relativearrangement to the pockets m, and said hopper is so mounted that it maybe readily shifted to permit the carrier to be placed upon and removedfrom the table. A nozzle p is preferably associated with each openingand is provided with a depending part intended to enter the open ends ofthe cartridge-shells in the carrier when the hopper is lowered onto thelatter. As illustrated herein,'tlie hopper is supported bycounterbalanced cables r.

In practice it is preferable to so arrange the hopper relative to themixing-machine that the latter will discharge directly thereinto, sothat not only the expense incident to the ordinary additional handlingof the explosive in transferring it from the mixing to the shell-fillingstations is saved, but the likelihood of foreign substance getting intothe mixture during such transportation is.

entirely avoided.

The means for rigidly connecting the hopper and carrier to the tableduring the filling operation is herein illustrated as a pair of clamps sin the forni of yokes mounted at the ends of the tables on'suitableeccentrics t. These yokes are intended to engage lugs on the hopper andforce the same down Jfirmly on the carrier and the carrier in turn downupon the table-top when the yokes are drawn down by shifting theeccentrics.

The form of hopper herein illustrated is intended for use in packing anexplosive mixture having a powdered or granular consistency; but when itis desired to load gelatin owders or explosives that are more or lessfluid when in a heated condition a water-jacketed hopper is employedwhich serves to maintain the substance in a warm condition forfacilitating the discharge thereof into the shells.

It will be understood that the accompanying drawings illustrate and theforegoing description describes but one embodiment of the invention andthat the invention is susceptible of varying embodiments withoutdeparting from the spirit and scope thereof. For instance, instead ofthe particular means herein shown and described for reciprocating andjarring the table cams may be employed for this purpose, the same beingarranged in a manner which would readily suggest itself to any mechanic.

I claiml. In a machine for packing explosives and in combination atable, means for giving the same a vertical reciprocating and a jarringmovement, a shiftable hopper supported above the table independentlythereof and provided with a plurality of discharge-openings, ashell-carrier having a plurality of shellpockets therein, said carrierbeing designed to rest upon the top of the table with its pockets inregister with the openings in the hopper and means for rigidlyconnecting the hopper, carrier and tables to one another.

2. The combination, in a machine forpacking explosives, with a hopper, ashell-carrier, a supporting-table, of means for imparting a verticalreciprocatory and jarring movement to the table, comprising a cylinderhaving an inlet in its lower end and an exhaust-port in the side wall adistance above the inlet, and a piston carrying the said table andcontrolling the exhaust-port.

3. The combination, in a machine for packing explosives, with a hopper,a shell-carrier, a supporting-table, of means for imparting a verticalreciprocatory and jarring movement to the table, comprising a cylinderhaving inlet and exhaust ports, a piston carrying the table andcontrolling the exhaust-port, and an abutment adjustable in the head ofthe piston for controlling the length of the stroke of the piston.

4. In a machine for packing explosives and in combination a table,ashell-carrier or shuttle having a plurality of pockets therein designedto be placed on top of the table, a hopper superimposed above the top ofthe table, and supported by counterbalanced cables, a plurality ofdischarge-openings in the bottom of the hopper having the same relativearrangement as the pockets in the carrier and'designed to registertherewith, funnels arranged in said openings having dependent ends ofthe shells within the shell-pockets of the carrier, means for rigidlyconnecting the table, carrier and hopper and means for imparting avertical reci rocatory and a jarring movement to the tab e,substantially as described.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Carthage, Missouri, this 31st day ofOctober, 1906.
